CHUR'N.

SPECIFICATION forming part of Letters Patent No. 436,605, dated September 16, 1890.

Application filed February 4, 1890- Serial No. 339 ,163. (N0 model.)

To all whom it may concern.-

Beitknownthatl, ANDREwMAnIsoNLANcE, acitizen of the United States, residing at Industry, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Ohurns; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Theinvention relates to rocking churns and the mechanism for operating them, my special object being to make the churn vibrate with the greatest facility and the least labor.

Figure 1 of the drawings is an elevation of one side of the frame; Fig. 2, an end elevation, and Fig. 3a vertical section.

In the drawings, A represents the frame,on which is erected two vertical parallel posts 13 13, connected by the spacers O 0.

Above the spacer O isjournaled in the posts B B a vibrating shaft D, to the middle of which is made fast the center of a segment E, the latter being provided with a peripheral groove e and a midway staple c. This staple is connected by two cords of equallength with the opposite ends of a churn G, so as to throw the weight of the churn and its contents equally on each side of the shaft D.

On the bottom of the churn are attached arms 9 g, which hang, respectively, on opposite sides of the spacer O, on which the churn has no bearing whatever. The object of the arms g g is to limit the longitudinal motion of the churn, while it is allowed to vibrate freely, as well as to have an up-and-down movement.

I may provide an arm H with an adjustable 40 weight I to vibrate the shaft D, or may use a crank on one end of the shaft and connect it with the wrist-pin of a hand-cranked wheel by a pitman of suitable length to vibrate the shaft in the desired arc of a circle. The weight I does not have to he lifted on the up stroke, because the milk, as soon as the churn moves one end on a downward incline, runs to that end and overbalances the weight. Hence as soon as the inertia of the weight is overcome it is raised by the collection of the milk in one end, While on the downstroke it greatly lessens what would otherwise be the weight to be overcome. It must not be forgotten that all the milk is alternately on the opposite sides of the axis of vibration of the churn.

In practice I find that by combining a vibratory motion with an up-aud-down movement I cause the butter to come in a surprisingly short time, While the laborrequired to operate the churn is very small indeed.

WVhat I claim as new, and desire to protect by Letters Patent, is

The frame A, having the posts 13 B, spacers O O, and a journaled vibratory shaft D, carrying the grooved segment E, stapled at e, in combination with a churn G, suspended from said segment-staple by two cords of equal length and provided with the subjacent arms 9 g, straddling the spacer O, as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ANDREW MADISON LANCE.
